装置共用および調停のための方法および装置
Document Type and Number:
Japanese Patent JP4210042
Kind Code:
B2
Abstract:
In a system in which control-capable nodes are coupled to each other and one or more devices via a communications bus, the control-capable nodes determine the identity of an owner node of a given device and register with the owner node for notification of changes to the device's ownership. The control-capable nodes may request ownership from the owner node, which request may be granted or denied, or the control-capable nodes may detect that ownership by the owner node has terminated. It such a request is granted, or if such termination is detected, the control-capable nodes attempt to establish ownership of the device according to previously assigned priorities. Data structures supporting these operations provide communications between device drivers and bus drivers in a control-capable node, and provide communications between bus drivers in different control-capable nodes. In this manner, the present invention provides a technique for device arbitration that does not require modifications to, nor participation by, the controlled devices.
